South Dakota Corn Performance Tests, 1956

Yield trials on those corn hybrids currently most popular among farmers are conducted each year by the Agronomy Department of the South Dakota Agricultural Experiment Station. The purpose is to supply farmers and ranchers with information on the relative performing ability of the various hybrids when they are subjected to similar environmental conditions such as rainfall, soil moisture, and fertility level. Such information, when used as a guide in selecting hybrids for planting, can aid the farmer in obtaining maximum yields under his field conditions. In 1956, fourteen tests were planted throughout South Dakota. Each contained from 20 to 40 entries planted in replicated plots. Yields, moisture percentages at harvest, and in some cases lodging and dropped ears, were obtained and are presented in the tables in this publication. Most areas of the state entered the 1956 season with low reserves of subsoil moisture. Temperatures approached long time averages in May but June was exceedingly warm at all locations, averaging several degrees above normal. Rapid and succulent early growth of corn resulted. This, coupled with severe drought conditions throughout the season caused an extremely poor corn crop in the usually productive southeastern part of the state, even though July and August were unusual in that their temperatures were below those of June. Elsewhere in the state, such as at Brookings and Watertown, above average rainfall in July and August, coupled with the relatively cool temperatures, resulted in excellent yields of corn in spite of the low springtime soil reserves. An early frost on September 6 killed the corn prematurely in some areas, such as the test at Claremont. This, coupled with high winds during much of September and October, caused a great deal of stalk lodging and dropped ears by the time the trials were harvested

Date and Rate of Corn Planting

Corn is South Dakota’s most important grain crop. It is grown on 4 million acres annually. South Dakota ranks ninth among the states as a corn producer, having one-twentieth of the national acreage and one-thirtieth of the production. The state may be divided into three areas on the basis of the place of corn on the farm: the eastern area, where corn is complementary to wheat and grazing; and the western area, where corn is supplementary grazing

Irrigation Research in the James River Basin: A Five-Year Progress Report

The prospect of irrigation in the James River Basin has created much interest in the past few years. To provide a scientific foundation and proceed with a minimum of costly trial and error, research on crop varieties, soil fertility and management, pastures, and water management was increased in the area in 19 4 8. Experiments were conducted on non-irrigated and irrigated land to determine the results and benefits under each condition. The expanded research work was conducted primarily on the Huron Development Farm and the Red field Development Farm

1947 Corn Performance Tests, South Dakota

Each year the Agronomy Department of the South Dakota Agricultural Experiment Station conducts corn yield trials on commercial hybrids and varieties in order to make available impartial information on the relative performance of the entries included when they are grown at certain selected places in the state. Information includes yielding ability, maturity requirements and other characteristics. Entries in each test are those hybrids which have enjoyed the greatest popularity on the basis of sales\u27 volume during the previous year for the area represented by that test and well known open-pollinated varieties which have been used in that area. The areas represented by the tests are those into which the state might be divided on the basis of soil type, elevation, rainfall and length of growing season

Spontaneous cerebellar hemorrhage in a patient taking apixaban

AbstractObjectivesAtrial fibrillation is closely associated with cardioembolic stroke. Until recently, warfarin has been the gold standard for the treatment of atrial fibrillation. Since 2010 the United States Food and Drug Administration has approved three new agents for anticoagulation in patients with atrial fibrillation. The purpose of this case report is to discuss some of the practical implications for using these agents.MethodsA patient taking apixaban presented with a spontaneous cerebellar hemorrhage. While the patient was initially considered a candidate for surgical intervention, the lack of literature addressing surgical intervention in patients on novel anticoagulation clouded the clinical decision-making. The patient was ultimately managed with administration of activated prothrombin complex concentrate, blood pressure control, frequent clinical assessments and airway protection. The patient did not undergo craniotomy for hematoma evacuation.ConclusionsRecent FDA approval of several novel oral anticoagulants for use in patients with atrial fibrillation has resulted in a significant number of patients formerly treated with warfarin being switched to these newer agents. There remains a lack of clear guidelines for the management of hemorrhagic complications. This case report describes one management strategy and highlights the paucity of current evidence to support critical clinical decisions

Methods for Managing Human–Deer Conflicts in Urban, Suburban, and Exurban Areas

This monograph identifies challenges and benefits associated with many human–deer conflict mitigation actions as well as methods to monitor the response of deer populations to management actions. Deer exploit urban, suburban, and exurban areas where human populations provide anthropogenic attractants, either intentionally or inadvertently, which often leads to human–deer conflicts. Mitigating actions have varying degrees of efficacy and may not be effective or accepted in every situation. Wildlife and municipal managers must work together to seek methods to reduce attractants, mitigate conflicts, and perpetuate the conservation of wildlife species that adds to the appreciation of nature in our lives.https://digitalcommons.usu.edu/hwi_monographs/1001/thumbnail.jp

SoundCloud and Bandcamp as alternative music platforms

We examine two ‘producer-oriented’ audio distribution platforms, SoundCloud and Bandcamp, that have been important repositories for the hopes of musicians, commentators and audiences that digital technologies and cultural platforms might promote democratisation of the cultural industries, and we compare their achievements and limitations in this respect. We show that the emancipatory elements enshrined in SoundCloud’s ‘bottom-up’ abundance are compromised by two elements that underpin the platform: the problematic ‘culture of connectivity’ of the social media systems to which it must remain integrally linked, and the systems of intellectual property that the firm has been increasingly compelled to enforce. By contrast, it seems that Bandcamp has been relatively stable in financial terms while being at odds with some key aspects of ‘platformization’, and we explore the possibility that some of the platform’s apparent success may derive from how its key features makes it attractive to indie musicians and fans drawn to an independent ethos. Nevertheless, we argue, even while in some respects Bandcamp acts more effectively as an ‘alternative’ than does SoundCloud, the former is also congruent economically and discursively with how platforms capitalise on the activity of self-managing, self-auditing, specialist, worker-users
